AIR-GUN.

Specification of Letters Patent.

Patented Feb. a, 19113.

Application filed January-2?, 1911. Serial No. 605,042.

To all whom it may concern:

Beit known that l, BURTON B. Bmvnn'rr, a citizen of the United States of America, residing at Plymouth, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Air-Guns, of which the following is a specification, reference being had therein to the accompanying drawings,

The invention relates particularly to air guns of the reciprocating barrel type, the latter serving as the means for compressing the spring.

One of the primary objects of the invention is the provision of means in a gun of this character for preventing, firing until the barrelafter the spring has been cornpressed-is restored to its outer shooting position, the object being to eliminate any possibility of injury by reason of the outward movement of the barrel projected by the released spring, or injury to the barrel abutment or seat resulting from the barrel being thrown forcibly against the latter.

A. further object of the invention is to provide simple and effective means for guiding the plunger stem into engagement with the trigger, and a still further object is the provision of a construction wherein the stem during the operation of firing is prevented from following the trigger, thereby insuring quick and effective separation of the parts.

With the several objects in view, the invention consists in the novel construction of the air gun, in the peculiar arrangement and combination of parts, and in various details of construction and in their arrangements and combinations, as will be more fully hereinafter set forth and claimed.

For the purpose of illustration, 1 have shown my invention as embodied in a toy air pistol, in which-- Fi ure l is a. vertical central longitudinal section, showing the parts in their relative positions immediately after firing; Fig. 2 is a similar view, showing the pistol in tensioning position; Figs. 3 and 4 are detached perspective views of the plunger andbarrel; Fig. 5 is a similar view of the handle section; and Fig. 6 is an enlarged sectional perspective view of the trigger mechanism.

In the drawings thus briefly described, the reference letter A represents the handle section, composed of the handle proper or grip B, and an open-ended housing C.

D represents the reciprocating barrel mounted within the housing for longitudinal movement, and E is the usual plunger housed within the barrel and adapted upon extreme outward movement to strike against an abutment a formed by a re-bent section of the barrel extremity.

F represents the plunger stem, having a substantially circular cross section for a .dis-

tance from the plunger, and for the balance I of its length-indicated by the referenceletter bpreferably a polygonal cross section, the stem presenting a flat-surface for abutment against the bottom of the barrel for the purpose of preventing any relative rotary movement. At its inner end the stem terminates in a hook c ada ted to engage the trigger, and immediate y adjacent to the hook in a concave bend d the purpose of which will be hereinafter set forth.

Gr represents the plunger spring, coiled about the stem, abutting at one end against the plunger head and at its opposite end against a cross pin J fixed within the forward portionof the open-ended housing B. This pin projects through longitudinal slot-s K in the barrel, and when the plunger is at its extreme outer position lies within the bend d in the stem, thus allowing the stem to properly travel over the bottom portion of the spring.

L represents the trigger, mounted upon a pivot 6 extending crosswise through the housing at its rear end andthrough slots 7 in the barrel. In addition to the usual detent g, the trigger is provided at its upper end with a projection it that normally bears against the top wall of the barrel except when the latter is in its outermost position, when it is adapted to engage an aperture 2' in the barrel top, the opening being sufiicient to allow enough movement of the trigger to disengage from the plunger stem. The'finger portion j of the trigger projects downwardly through a suitable slot is formed longitudinally in the bottom portion of the barrel for that purpose.

Referring to Fig. l of the drawings,

ing position before any firingcan take place.

The crosspin J, in addition to serving as an abut-ment for the spring, acts as a guide for the stem, insuring the proper engagement of the latter with the trigger detent. This latter function is effected by the pin bearing against the top portion of the stem, causing the bend in the latter to travel upon the bottom of the barrel, and, through the curve of the stem, into proper engagement with the trigger. The bend d by contacting with the barrel acts as a support for the trigger-engaging portion of the stem, preventing any downward or follow movement of the latter with respect to the trigger dur ing the operation of firing. Thus, a quick and effective break between the parts is provided for.

In most instances, the opening 2' formed in the upper wall of the rearend of the barrel is sufiicient to afl'ord the necessary I play for the trigger to disengage from the stem. I may, however, and preferably do,

form an alining opening 2" in the open-ended easing 1nto which the trigger projection may extend if necessary.

What I claim'as my invention is,

1. In an air gun, the-combination with a barrel, of a spring-pressed plunger and its stem, a trigger engageable with the stem, the latterhaving a bearing portion in advance of the part of the stem engageable with the trigger adapted to engage the barrel for preventing follow movement of the stem relative to the trigger during the disengagement of the parts.

2. In an air gun, the combination with a handle section, of the spring-pressed plunger, a reciprocating barrel acting on inward movement to compress the plunger spring, a trigger for holding the spring in its compressed position, and means for preventing release of the spring until the barrel is restored to its outer shooting position.

3. In an air gun, the combination with a handle section, of a spring-pressed plunger and stem, a reciprocating barrel mounted upon the handle section and acting on in noaanaa ward movement to compress the plunger spring, a trigger engageable with the stem for retaining the spring under compression, and a lock for preventing operation of the trigger until the restoration of the barrel to its outermost position has been effected.

4. In an air gun, the combination with a handle section, of a spring-pressed plunger and stem, a reciprocating barrel upon the handle section serving on inward movement to compress the plunger spring, a trigger for engaging the stem after the compression of the spring has been effected, and a projection on the trigger bearing normally against the wall of the barrel and acting to hold the trigger against movement until the restoration of the barrel to its shooting position has been efl'ected.

5. In an air gun, the combination with a handle section, of a spring-pressed plunger and stem, a reciprocating barrel upon the handle adapted upon inward movement to 'compress the plunger spring, a trigger for engaging the stem, and a projection upon the trigger bearing normally against the barrel top and adapted to engage an opening in the 'upper wall of the barrel at the rear end of the latter.

6. In an air gun, the combination'with a barrel, of a spring-pressed plunger housed therein provided with a stem, a trigger engageable withfthe stem, a pin extending transversely of the barrel forming an abutmentfor the spring, said stem being arranged beneath the pin, whereby the latter forms a guide for positioning the stem in proper relation to the trigger during the charging or setting of the parts.

In an air gun, the combination with a handle section including anopen-ended housing, a reciprocating barrel provided with slots, a spring-pressed plunger includ ing a stem, s'aid'barrel acting on inward movement to compress the plunger spring,

a trigger for holding the spring in its compressed position, a cross pin carried by the housing and extending through the slots in the barrel, forming a guide therefor, and an 'abutmentfor the spring, said pin being arranged above the stem, whereby it serves as a guide for positioning the stem in proper relation to the trigger during the charging or setting of the parts.

' In testimony whereof afiix my signature in presence of two witnesses.
